大功率变频器在抓斗行车上的应用

The Application of High-power Inverter in the Grab-crane

本文介绍了艾默生大功率TD3000变频器在抓斗行车的运用。抓斗行车变频改造后,很好地解决了主/闭钢丝绳受力平衡问题,软启软停方式大大降低了起制动时的冲击电流,再加上变频器本身具有完善灵敏保护功能,极大地提高了行车运行的可靠性,延长了系统的使用寿命。

This text introduces the application of Emerson high-power TD3000 frequency converser in the grab-crane. After the conversion of the grab-crane, the problem of the bearing balance of the main/closed steel wire rope is well solved, the soft starting and soft stopping method greatly reduces the impulse current at the time of starting and braking, and the converser itself has complete and sensitive protection function, which greatly improve the stability of the operation of the grab-crane and prolong the life of the system.
